Be it known that I, ALVA LnEMaNfRnY- NOLDS, a citizen of the United States, residing at Longbeach, in the county-of Los Angeles and State of California, have invented new and useful Improvements in Hydraulic-Power Systems, of which the following is a specification.

T his invention is applicable in connection with features of my-earlierinvention entitled improvements in water power systems, No. 988,508, patented Apr. 1, 1911,

and principally differs from said earlier invention in respect to the driving of the pumps whichv inthe earlier invention were driven by vertically pivoted vanes more particularly designed for utilizing the force of ocean waves whereas in this present ina flowing stream of water.

Another object is to effect the driving in such manner that fluctuations in the height of the stream caused by tidal action or otherwise will be compensated for.

Another object is to effect the-driving in such manner that power may be derived from a stream flowing atditferent periods of tin' iein reverse direct-ions as would .occur in tidal rivers.

Other objects and advantages may appear from the sub'joined detail description.

The accompanying drawings illustrate the invention.

Figure 1 is a perspective .view of apparatus embodying the invention. Fig. 2 is an enlarged fragmentary plan view of Fig. l, the pier floor being omitted to expose to view the parts beneath. section of a floating paddle-wheel on line 00, Fig. 2.

A turhino-generator set 1 or other hydraulically-operated device is connected in multiple by a pressure main 2,.sump 3 and supply main 1 to pumps 5 preferably double-acting; and the pressure main 2 may be provided intermediate of the turbine-generator set and pumps with an air-pressure tank 6 and a pressurc'gage 7, all of which have been substantially shown and specifically described and claimed in the herein- Fig. is a cross before mentioned patent and are not'herein claimed. In-this'instanee the'pump pistons 8 reciprocate through bearings 9 at their outer ends and are provided with wristblocks 10 which pivotvertically swinging pitmen 11 that-are connected to crank shafts 12 jeurnaled in bearings 18. Each crankshaft l2- -is provided at one end with a sprocket wheel 1A driven by a sprocket chain 1 5 --which is driven in turn-by a sprocket wheel 16 rotatably mounted on a hanger shaft17=that extends between supports as the'piles IS'and-that is suitably fastened at its ends by sockets 19 and bolts 20 to the'piles and that may be supported intermediate'of its ends by hanger brackets .21 which are fastened by means, not shown, to the pier floor a. Each sprocket wheel 16 is driven by-a'nd may be integral with a bevel gear .22 meshing with a bevel gear 23 fixed on one end of a gear shaft 24 which is provided at its other end with a bevel gear 25 and which is journaled by bracket bearings 26 that are supported on one of a pair of spaced-apart radius 27 which :are pivoted at'their upper ends by journalboxes 28 tothe'hangershaft 17. By this construction it is seen that the bevel gear 23 can swing in an arc of which its generating :axis is coincident with the axis of the bevel 'gear 22.

The hanger with thrust collars29 on both sides of the radius arms to keep them from sliding along the shaft. The radius-arms 27 of each pai= are provided at their lower ends with boxes 30 journaling awheelshaft 31 which is provided with a bevel gear 32 in mesh with and driving thebevel gear 25 and on which is mounted a buoyant paddle wheel 33 to drive the wheel shaft.

From the foregoing it is clear that any up-and-down movement of the paddle wheel 3? will notaffect the driving connections "and it is also clear that the driving connecions may be otherwise constructed to 0b- "tain this result. v v a The wheel-shaft 31 may be suitably provided with thrust collars 29 to prevent endwise movement of the paddle wheel 33. Each paddle wheel in its preferred form of construction comprises a cylindrical shell 34 of metal or wood having longitudinal slots 35 through which vanes or paddles 36 of metal or wood project radially inward to seat at their inner ends in longitudinal shaft 17 may be provided shaft 3l and to which the paddles may be fastened by bolts 39 or the like. The inter paddle spaces 40 are filled with suitable material to etl'ect such buoyancy of the pad- -dle Wheel as will keep the wheel shaft 31 above the level of the water 42 and I have shown such material as a bouyant solid which may be composed of a composition 41 of ground cork.andasphaltuin. The interpaddle spaces .40 may be filled with the ground cork, and hot asphaltum then poured in so as to seal the shell and efi'ectually exclude water fromthe interior, thus making the paddle wheel buoyant and at the same time bracing the paddles against the thrust of the stream on their outer projecting ends.

Inpractical operation the radius. arms 27 will extend in the direction of the current shown by small arrows and the paddle wheels 33 .will; rise or fall in accordance with the level of the water l2 and will drive the pumps 5 through the driving connections to eti'ect operation of the turhino-generator set 1 as set forth in .my hereinbc'tore mentioned patent.

in tidal rivers when the current reverses the tide ebbs and tlows .the direction of rotation of the paddle wheels will be accordingly reversed, without any detrimental etlect ou the pump driving mechanism.

By constructing the paddle wheel in the manner set forth is made practically nonsinkable and non-collapsible thus guarding againstv submersion. caused by leaks and also against brealeigc from floating bodies in the stream.

I claim p 1. In a hydraulic power system, a paddlewheel comprising a shell and 'a' buoyant composition of cork and asphaltum in the shel 2. A paddle-wheel comprising a shell with longitudinal slots, a core sleeve having Ion-- longitudinal slots, paddles extending radi ally inward through the shell slots, and a buoyant filling in the inter-paddle spaces of the shell.

5. A paddle-wheel having a ,shell with longitudinal slots, paddles extending radially inward through the shell slot's, and a buoyant composition of cork and asphaltum in the shell.

6. ,A paddle-whee] having a shell with longitudinal slots, :1 core-sleeve having longitudinal grooves, paddles extending through the shell slots and into said. grooves and a filling in the inter-paddle spaces 0 the shell.

7. A paddle-wheel having a shell with longitudinal slots, a shaft, a core sleeve fixed to the shaft and provided with longitudinal grooves, paddles extending through the shell slots and into said grooves, and afilling in the inter-paddle spaces of the shell.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 8th day of August, 1912. i i
